More questions... Way down to the line, but I feel the need to know now. LOL

For inside the egg tub, it sounds like substrateless/just straight water with an egg crate on top is fine. What do you use to raise up the egg crate higher out of the water so that air can circulate above and below the eggs?

Also, I read around that egg crate is dangerous for hatchlings to crawl around on. So how soon after the first egg pips can I move all the eggs onto just damp paper towel? What should the humidity be at after the first pip? Still 100%?

When do you take out all the hatchlings out of the egg tub and into a normal setup with holes in it, on a heat pad? After they all finish coming out, or just after the first pip? And... at what point in this whole process should I start to lower humidity from 100%?
